1．试编写程序：在8位LED上按照从左到右的顺序，依次显示0～7八个数字。
2．将定时时间逐渐加大，直至LED发生闪烁为止。计算此时LED数据更新频率。
1. Test preparation programs: the 8-bit LED on the order from left to right, followed by eight digits 0 to 7 displayed. 2. Gradually increase the regular time, until the LED flicker up. LED data update frequency calculations at this time. (2011-05-02, Asm, 10KB, 下载2次)
1．试编写程序：INT0外部中断。P1口接8个LED，4个为一组，交替亮灭，当INT0出现低脉冲，响应中断，显示流水灯效果。
2．试编写程序：T0计数中断。P1口接8个LED，4个为一组，交替亮灭，当T0计数3次，响应中断，显示流水灯效果。
3．试编写程序： T0定时中断。P1口接8个LED，4个为一组，交替亮灭，当T0定时器定时3秒中断，显示流水灯效果。
1. Test preparation programs: INT0 external interrupt. P1 port connected 8 LED, 4 in groups, alternating light off, when the INT0 low pulse occurs, the response disruption, showing water light effects. 2. Test preparation programs: T0 counter interrupt. P1 port connected 8 LED, 4 in groups, alternating light off, when the count of 3 times T0, response interruption, water light show effects. 3. Test preparation programs: T0 timer interrupt. P1 port connected 8 LED, 4 in groups, alternating light off, 3 seconds when the T0 timer interrupt timer, display light water effects. (2011-05-02, Asm, 12KB, 下载7次)
